Turn on default MS Word Editor in Smartforms SAP S/4HANA

If you are here, means that you encountered the slow performance when opening the text editor on smartforms, on the previous SAP ECC 6.0 System, you can apply Note OSS 2221815_2221815 – SAPscript Legacy Text Editor , and then change the preference on rscpseteditor program.

However, since you are using SAP S/4 Hana, you cannot do this anymore, regardless if you are using SAP GUI 7.4 or 7.5. you need some extra configuration a.k.a. Enhancement. How is it done?

1. Go to SE24
2. Open Class CL_COS_UTILITIES 
3. Go to method IS_S4H
4. Create an enhancement at the end of the method
5. Insert the following code

IF SY-TCODE = 'SMARTFORMS' OR SY-TCODE = 'SE71'.
  RV_IS_S4H = abap_false.
ENDIF.

The method is used by SAP to check whether the system is S/4 HANA or not, hence the enhancement tricks SAP GUI to tell that it is not S/4 HANA System when you open/use TCODE SMARTFORMS or SE71
